Sunday, Aug. 25 to Saturday, Aug. 31 from 10 p.m. to 5 a.m. each night, Dulles Corridor Metrorail Project (DCMP) crews will be installing down spouts on the pedestrian bridge at Innovation Station, requiring the full closure of the slip ramp from the eastbound Dulles International Airport Access Highway (DIAAH) to the eastbound Dulles Toll Road (DTR) at mile marker 1.7, nightly.This closure will restrict access to the Centreville Road exit on the DTR for eastbound DIAAH traffic. A detour will be put in place to bring traffic from the eastbound DIAAH to Centreville Road by crossing over to the DTR at the next slip ramp (MM 2.7) and taking the exit for Fairfax County Parkway, following signs to detour along Sunrise Valley Drive. See graphics for detail below.

All work is weather dependent and subject to change. Drivers are asked to use caution and pay attention to all signage and barricades. Large, slow-moving vehicles may be exiting and entering the highway at various times.
